` Application `filed July 16, 1883. (No model.)

To all whom t may concern:

Beit known that I, GEORGE C; BAKER, of

i Des Moines, in the county of Polk and State ranging, and combining barb-feeding, barbpressing, barb-notching, barb-cutting, barbbending, barb-spacing, and barb-fixing mechanism with a single driving-shaft, as hereinafter fully set forth, in such a manner that `barbs can be successively formed at regular intervals from a round wire or dat metal strip and placed astride of a fence-wire by the rectilinear motions of the cutter, andthe barbpoints thencrossed and bent in `opposite directions and firmly fastened upona fence-wire by the joint action of two horizontal slides in place of the intermittent motions of rotating coiling devices heretofore generally used for applying barbs to fence-wire.`

Figure l of my accompanying drawings `is a side view. Fig. 2 is a sectional view of the sprocket-wheel; Fig. 3, a top view, and Fig. 4 an end view, of my machine. Figs. 5 to 23, inclusive, are detail views, and all correspond in size with the scale of Figs. 1, 2, and 3,l eX- ceptng Figs. 7, 8, 9, 10, 16, 19, 20, 22, and 23, which figures `are made on an enlarged scale. Jointly considered ,these figures clearly illustrate the construction and operation of my complete invention.`

A is a metal base-plate rigidlyxed upon a suitable frame, preferably a cast-metal frame.

B is the driving-shaft, mounted `in bearings fixed to the frame to extend horizontally across underneath the plate A.

B is a belt-wheel-,ixed to the end of the v shaft B.

` B2 is a belt-wheel designed to transmit power from the shaft B to reeling and twisting mechanisms. (Not shown.)

f C G are brackets fixed to the front end of y `the frame and base A. .t i

C' is a shaftmounted inbearings fixed to thebralckets C.

(from-a spool, not shown) to the duplex 6o sprocket-wheel C2.

D is a friction plate, hinged to the crosspiece C4 in such a manner that its under side will rest iiat upon the top surface of the crosspiece and the parallel fence-wires extending under it.

D are arms extending laterally from the opposite sides of the plate D, from which arms a weight, D2, is suspended by means of cords a, as clearly shown in Fig. 1, to produce fric- 7o tion sufficient to keep the parallel `wires stretched tight around the sprocket-wheel, as required, to be advanced tothe barb-forming and barb-fastening mechanisms at regular intervals of time to have the barbs fixed thereon at regular distances apart.` y `E is a ratchet-wheel fixed to the end of th shaft C.

E is a lever pivoted on the same endof the same shaft and on the outside of the ratchet- 8o wheel. A pawl, a', pivoted to the free end of the lever, engages the teeth of the ratchetwheel. t

. F (clearly shown in Fig. 13) is an eccentric fixed to the driving-shaft B.

F is a collar formed in two sections, placed over and loosely around the periphery of the eccentric.

F is a pitman-rod connecting the collar F and the pivoted lever E in such a manner that 9o every revolution of the shaft B and eccentric F will impart an intermittent motion to the shaft G and the sprocket-wheel C2 and advance the parallel wires.

` a (clearly shown in Fig. 1) is a trip-lever, 95

ratchet-wheel E. roo

b is a spring fixed to the door and the lever a in such a manner that in its normal/posi- The bearings for the two 55 tion it will hold the pawl a in contact with one of the teeth of the Wheel E2, 'as required, to retain the sprocket-wheel C2 and the parallel 'fence-wires stationary at regular intervals of time and space while the barbs are being fastened to one of the parallel wires.

b is a cam on the end of the driving-shaft B, that engages the short arm of the trip-lever a at every revolution of the shaft and depresses it to lift the pawl a, as required, to free the shaft C and wheel C2, and thereby allow the parallel wires to be advanced at regular intervals. v i

G' (clearly shown in Figs. 3and 5) is apost fixed on the top and center of the base A, to support barb-cutting mechanism.

c is a movable frame below the base'A, that has extensions c and c, that project toward the shaft B.

and 6 are cams fixed to the shaft B, to engage the extensions, and thereby alternately lift and depress the frame c.

d cZ are bolts fixed in parallel position to the i frame c at their lower ends, and to a crosshead,d, at their top ends. They extend through bearings formed in the inclined portion ofthe post G.

d is a barb-cutter and barb-bender, made of a plain angular piece of steel, xed to the cross-head cZ. It has a transverse groove across its square bottom, as clearly shown in Fig. 14, to engage a straight barb-piece when it extends horizontally over one of the fencewires, and bend it double and astride of the wire preparatory to bending the ends of the barb in opposite directions across the fencewire, as required to fasten it to the wire, and

. as shown in Figs. 16, 17, 21, and 23.

f (shown in Figs. 3, 5, 18, 21, 22, and 23) is a stationary cutter fixed on the top of the b'ase l A in parallel position, with the parallel wires Vin such a position that the square edge of the vertically-moving cutter .and bender d will cut off a barb every time it descends past the square end and cutting-edge of the horizontal cutter f. p

j is a bar xed on the base A at right angles to the cutter j' and against the rear end thereof.

f is ablock fixed across the cutter fand upon the foot of the post G.

f (shown in Figs. 3 and 7) is a guide fixed on the top of the base A in an inclined position relative to the square cutting-edges of the cutters d and. j', to direct a flat metal strip to the cutters. Y A

g (shown in Figs. 3, 12, and 7) is a short shaft, mounted on the base 'A by means of bearers g at right angles to the inclined guide f.

h is a feed-roller fixed to the shaft g.

h is a pinion fixed to the same shaft.

f h (clearly shown in Fig. 12) isvone of apair of brackets xed on the under side of the base A, to support an adjustable shaft-bearing, z'.

la is a shaft mounted in the bearings i in parallel position, with the shaft g on the top of the base. A second pinion, h", is fixed to the shaft 7c, to engage its mating pinion on the shaft g. An Vopening in the base A allows these mating pinions and feed-rollers to come in contact with each other.

k (shown in Figs. Land 8) is a cam fixed t6' the shaft B.

7c is a rack that extends vertically through an 'opening in the base A, and is connected with the shaft B at its lower end by means of a bridle. I A l k is a spring fixed to the top of the base A and the top of the rack 7a in such a manner that it will in its normal condition hold the rack up.

76 is an anti-friction roller attached to the side and lower end of the bridle and rack 7c in such a manner that it will be engaged by the cam k at every revolution of the shaft B, and the rack thereby depressed.

Z is a pinion placed loosely upon the shaft g to engage the rack 7c.

Z is a flange formed integral with the end of the pinion Z. 1

Z is a pawl pivoted to the face of the flange Z, to engage a ratchet-wheel, Z, that is xed to the shaft g in such a manner that the dowuward motion of the rack will rotate the pinion, and also the shaft, but rotate the pinion only in its upward motion, as required to transmit intermittent rotary motions to the shafts g and kand their mating feed-rollers h, for the purpose of advancing a flat metal strip through the guide f, to be cut into barb-pieces of uniform length at regular intervals.

m m are projections on the peripheries of the upper feed-roller, h, at regular distances apart, and on the opposite edges of theroller. Corresponding depressions are formed in the under feed-roller in the manner roller-dies are made, to make the feed-rollers perform the function of barb-notches and to cut notchesin the opposite edges of astrip of barb metal as it is advanced between the rollers, for the purpose of producing the patented barb hereinbefore referred to.

m are set-screws that extend through the brackets h and into the bearings of the shaft k, for the purpose of adjusting the shaft kand the lower roller or die, h', relative to the upper roller, h, and shaft g. By means of this adjusting device a wire may be readily pressed flat as it is passed through between the feedrollers, as shownin Figs. 6 and. 7. y

m (shown clearly in Figs. 5, 22, and 23) is a dat bar on top of the horizontal cutter. Its front end is cut off diagonally to form an inclined shoulder and guide to direct the end of the fiat metal strip relative to the cuttingedges of the cutters, as required to cut off a barb-piece.

m (shown in Figs. 3 and 5) are frictionplates placed under the guide-plate f, one on top of the knife f and the other on top of the sliding bar mm. Y

n are set-screws that extend through the .lOO

IIO

vt, in its top and center, and with doWel-pins n at its bottom. i This bar is placed upon the base A in such a position relative to the cutters d and f that the center of each barb' will be over the center of the notch n and the finger n of the sliding bar mm inthe notch when the cutter and bender descends to sever the barb and to bend its points downward on opposite sides of the bar n, as required to place the barb ast-ride of the fence-wire.

g qlllll/ll press the sliding bar mm and its finger n through the notch n of the bar n.

o o are sliding barb-benders, provided with extensions o at their ends, that are adapted in form to engage the ends of the barbs after they are doubled overthe fence-wire, and to press them in opposite ldirections and into crossed positions, as shown in Fig. 17, and as required to fasten it to the wir'w o is a cam on the end of one of the slides o, that engages the end of the bar mf and pushes it backward relative to the spring if, as required to withdraw theV finger n before the ends of the barbare crossed under the fence- Wire. The' under part of the end of the cutter f is cut away to admit the cam o. i

r r are cam-wheels fixed to the shaft B to engage studs r onithe bottoms of the slides .o in such a manner that they will impart reciprocating motions to the slides at every revolution ofthe shaft B.

r" are bearings for the slides o, xed to the' base A.

s (shown in Figs; 3 and 15) is a plate xed to the base A, to keep the two parallel fencewires separated until after the barbs are Xed on the upper wire. A groove in the surface of the base-plate A allows the under fencewire to pass, and a groove in the bar mf allows the upper Wire to pass in parallel position with the under one until the barbs are fixed upon the upper one, when the two is a' spring fixed to the bar f in such a" manner that it will in itsA normal condition strands are twisted together, and the complete barbed cablel coiled upon a spoolat the rear end of the machine.

From the foregoing detailed description of the construction and function of each element and sub-combination, the unitary actions of 'all the parts and the practical operation of my complete invention 'will be apparent to all persons familiar with the art to which it pertains.

I claim as my invention- 1. In a wire-barbing machine, a pair of feed-rollers having coinciding projections and notches in the opposite edges of their peripheries, to `adapt them to notch the edges of a metal strip as it is advanced toward the barbcutters between the rollers.
